Factors determining the invasion of Bromus tectorum L. (Poaceae) (Directed by Karina Speziale)
We are evaluating the biological and ecological traits of the invasive grass Bromus tectorum in NW Patagonia so as to predict its capacity to expand its range under current environmental conditions. In particular, we are studying the effects of routes as the starting...
Granivory and seed dispersal by ants in arid ecosystems
We are studying ants involved in seed consumption and/or dispersal in the Patagonian steppe, and their effects on plant community as well as implications for plant biological invasions and restoration of degraded ecosystems. In particular, we have studied diet and...
Ecosystem services provided by ants and their implications for biological control and ecological restoration
The provision and continuity of several ecosystem services are currently threatened by land use, agriculture practices, deforestation, habitat fragmentation, climate change and biological invasions among other factors. Thus, there is an urgent need to identify and...
Direct and indirect effects of ants on plants
Leaf-cutting ants can affect plants negatively directly through defoliation, but positively and indirectly increasing the soil nutrient level. We study these effects separately and together, to determine the relative importance of leaf-cutting ants on plants that grow...
